Right, because you are linking to the static Xerces-C++ library which
was configured with threads enabled, any library/executable that links
to Xerces-C++ will also need to explicitly link to the pthread library.

The way to do this is to enter -lpthread when asked for extra C++
libraries during the configuration phase. If you don't want to
reconfigure everything, you can just edit the
build/cxx/configuration-dynamic.make and add this value to the
cxx_extra_libs variable.
